Cupping has been found to pull the fascia (connective tissue) up to 4 inches deep in the body! It's effective in breaking up fascial adhesions, chronic muscular contractions and patterning, and brings blood to the surface (it acts like a reminder for the body to use lymph to clean up that area). 5 minutes of cupping is equivalent to 30 minutes of deep tissue work. (I can't say enough good things about it!)
